Perhaps it was just an isolated few that had issues I don't know, just trying to make the right choice between the new 65mm SC pulley and an ASP 178 pulley. I know; it's an old debate. I'd also like to know how EC is doing it better than the C3, or is it just a copy? Will have to wait and see.
Weird, I have never heard of drivability issues with a SC pulley. As far as the build quality, the only thing I have heard of/read was the grooves wearing the belt slightly on the Code3 (Gen 1) SC pulley and a few that needed to change out the bearing (Gen1 & 2). But that will happen with any pulley after time as they are all using the OEM bearing. You have to take into consideration the individual use of each it item also. ie: velociabstract autocrosses his car quite a bit, so he would be on/off with the supercharger a lot during his races.
